Boston Celtics’ coach Joe Mazzulla announced that Luca Garza is sidelined indefinitely due to a concussion sustained during Wednesday’s game. Garza’s absence, though expected to be brief, opens up opportunities for Neemias Queta, Chris Boucher, and Xavier Tillman to fill the void in the center position. Upon his return, Garza is anticipated to gradually regain minimal playing time from the trio.
